I am lost what you are talking about.
i thought below command which you gave – will work as variable.
if (get_field(‘subtitle’)) {
?><h2><?php the_field(‘subtitle’); ?></h2>
}
?>
In previous screen – i put subtitle as “This is subtitle” on subtitle field when creating a post, but when i visit the post – post has code above screenshot code instead of “This is subtitle”
It meant which code you gave is not calling ‘subtitle’ field to display in front-end?
